CALCULATING ZIAGEINE.

Specification of Letters Patent,

Patented Sept. 2, 1913.

Application filed January 30, 1912. Serial Ro. 874,241.

calculating machines, and more particularly to calculating machines of that class, in which the values of the calculations are set on a plurality of setting disks by shifting the desired number 01" teeth into operative position, and transferred to numeral wheels by rotating the setting disks by means of a crank. To permit continuous multiplications of the form etc to be performed bymeans of machines of this class two sets of numeral wheels are arranged one beside the other on a common slide or carriage, and the said sets of unineral wheels cooperate with two sets of setting disks which are likewise arranged one beside the other.

One of the objects of the improvements is to arrange the setting disks and numeral wheels in such a way, that the machine can be usedas well for performing the continuous calculations above referred to or, if desired, a single calculation of exceptionally hi h numbers.

ith this object in view my invention consists in arranging the sets of numeral wheels without interruption one beside the other, and in such a way, that each set of numeral wheels can be used in combination with the adjacent setting mechanism, or, if

desired, and where calculations of enceptionally high numbers must be performed, that both sets of numeral wheels can be used as a sin le one in combination with one of the sets 0 setting disks.

Furthermore my invention consists in so constructing the revolutions counting mechamsm for counting the revolutions of the setting disks (or. the crank), that the single toothfloperating the revolutions counting mechanism remains in operative position relatively to the latter, even if by shifting the earns ,the set of numeral wheels lo' cafed at 6 left hand side of the. carriage has been brought into cooperation with the set of setting disks located at the/right'hand side of the machine.

clearly understood an example embodying the same has been shown in the accompanyin drawings, in which the same letters of relbrence have been used in all the views to indicate corresponding parts.

In said drawings-Figure 1, is a front view of a calculating machine of known construction in which my invention may be embodied, the casing of the machine being i partly removed, Fig. 2, is a cross-section taken along the line 2-2 of Fig. 1.

Reference will now be had to the drawings.

A rotary shaft 63, mounted in a pair of side walls 61 and 62, is operatively connected with the machine crank 64 through spur gears 65'and 66, and it carries a plurality of setting disks 67 each of which is provided with nine' radially shiftable teeth 68, engaged by a cam disk 69. In front of the said settin mechanisms 67, 6'8, 69, 69, numeral w eels 7 are loosely mounted-on a shaft/9, disposed parallel to the shaft 63. Each numeral wheel, the'numerical characters of which are visible through. a peep hole 72 in a cover 72, has a spur gear 73 which is'in mesh with the teeth of a transmission wheel 13, looselyv mounted on a shaft 12. The said transmission wheels 13 fare locatedin the plane of the .r'adially shiftable teeth 68 of the fsettin disks 67.

Carrying means are provi ed between consecutive-numeral Wheels. In the example illustrated the counting wheels 7 are provided lovers 7 6, loosely mounted on a shafi; 76' disposed parallel to the axis 9. Thelcvers 76 extend with their free upper ends 7, in known manner in the I, ath of ins 7 of the numeral wheels 7, whereby t e levers'76 are rocked, when the numeral Wheelspass from their 9 position into their Olim- 'sition, or vice versa. Thereby a cam ace 76 of the rocking lever 76 is thrown into the path of laterally shiftable teeth 67" of the cooperating setting disk 6'7, adapted to cooperate, when shifted, with the transmission wheel 13' cooperating with" the numeral- Wheel "1' of the next'h'igher order.

In order that my invention be more with hammer-shaped carrying is connected with a l O of the numeral wheels. 6072' of both a Cam faces, 67', robkthelevers'76 into their normal positions shown At the left t me registeringmechanism 7 a second registering mechanism 7 8 is pro- 5 vided for counting the revolutions of the machine cranlnwhich revolutions counting mechanism is actuated from the shaft 63 by means of'a single tooth wheel 79 advancing a spur gear 80. Each of the numeral wheels ring 81, and all the.

gear wheels 80 meshm Wl'tit the gearings Slare loosely mounte on lL-Bllllfl'; 84 disposed parall lfl to the shaft 70. of the registering mec anism 78.

4 Both registering mechanisms 7 and 78 are provided with, resetting mechanisms adapted to set -the numeral wheels into their zero positions. At its outer end the shaft N9 carries a nutill, and .within each of the 7 it is proyided with a numeraL wheels lradia-l pin 9',- coiiperating with an abutment wheels 7. Upon rotation fvthe shaftj 9"by means oithe nut 11 the shaft 9 is shifted laterally against the action of aspring 89 by meansof a cam face 88, so that the pins 9', are-shifted into the path of,.-th'e rebut merits} 10.- whereby ,jth e wheels 7 are turnedto their zero positions. Resetting mechanisms, 0*; the same construction are provided on; the shaft 70wwhich carries a. nut 90 at its *outer end. Short sleeves 85-prevent the axial displacement of the wheels 7' and 78.

Referring now, more particularly tothe 3; construction forming my invention the reg istering mechanism which consists ofs the, sets of numeral wheels 7 and. the revolti' tions counting mechanism 78 are mounted on a common carriage or slide 1 which is 4o slidable in.a direction parallel to the shaft 63, so that the setting disks. 67 of the lower order (shown at the right inFig. 1-) can be brought into cooperation with 'the 'numeral wheels 7 of the higher'order (shown I at the left. in Fig. l).- @Whereby in case of multiplications withJliigh numbers the necessary number off-rei olutions. of the crank is reduced.

The carriage 1 carries sets ofjnumeralf '50 wheels 7 2 and-7 which-'are-- located coaxially with the revolutions counting mechanism 78, and each of which "cotiperates with a' setting mechanism 69. and '69 respectively, and the sets ofnumeral wheels are arranged without interruption .=;.one'- beside the other,

ordinary distance of the setting disks. The

division line betw'eeli-v numeral wheels may beindlcated by an y su table mark, for example by meansof an arrtiw 1' In a my improved calculating machine the set of numeral wli'eels 7 can'be used in co operation with the set of setting disks 69" andthe set of numeral wheels -7 can be used in co6peration with the set ofsetting disks69 as is known in machines of thisclass. However, apart from this, it exceptionally largev calculations must be performed, both sets of numeral wheels 7 and 7 can be used as a single set in coiiperation with the set 'of setting disks 69, for which purpose the carriage 1 is if necessary shifted to the right and in the direction of the arrow 1' until'the set of numeral wheels 73- is in position for cooperation with the set ting mechanism 69 v v Thenu'niber of he numeral wheels of-the revolutionscounting mechanism 78 must be such, that the single tooth whichislocated in the plane. indicated by the arrows in Fig. 1 is still in coiiperation with the revo lutions counting mechanism 78, if the carriage 1 has been shifted to the right into position with the numeral wheels 7 in cooperation with the setting mechanism 69 fThe apparatus can also be used without shifting the carriage to the right to such an extent as. described, because between the numeral. wheels 7' and 7 carrying means have been provided, so that large numbers :can be displayed by the combined numeral v If dfired aflarger coiiperates with its own registering mechasm, all the registering mechanis s being {located one besidethe other 1n uninterrupted succession.
